V i iE OR eOIfiKRio, c1nAnA-,-Assic;1von-"ro winm mir 'lrnorms i 1VIULLE-R,0FCOLTJINGWOODQONTARIO, CANADA.' i.
i i" niitrnivirlit revigeeei Be it known that-5 1, Gnoncn ficarvns,"ct the: village- 0f Creemoreg in' the county o fg Simcoe and- Province of Ontario, Dominion: of Canadap 11 are invented certain 'new'fan'd useful Im pro'vel'nents' in 'nirfl n'rnpsg; and-:1 hereby declare that 'tlie 'fol'lowing ii in full, clear, andx xact description of lill sit'lil'eij;
This? inventio r relates' to airaair pump in which-the pump *cyli'nd'er 'i's{rockably mount; ed 1 in 'a bearing bracket 'and the pistoniro is knuckled" to a pump handle; fulcr1imed"to a 1 which hold the cylinder casing and heads in H their assembled relation, each cylinder head having a valve-controlled air inlet, charging the cylinder when the iston is movin in one direction, and resisting the outlet of the air as it moves in the opposite direction, each cylinder head also having a back pressure valve-controlled air outlet, these air outlets being connectedby a header fitted with a flexible air conduit, and with a-gage for indicating the pressure therein.
In the drawings Figure 1, is a vertical sectional View of the pump showing the construction and relation of the parts;
Fig. 2, is an end View of the pump cylinder and the bearing therefor; I
Fig. 3, is a sectional elevation of the pump handle and bracket therefor;
Fig. 4, is a fragmentary view of the pump handle;
Fig. 4:, is a fragmentary view of the pump handle taken at right angles to the plane, shown in Fig. 4:;
Fig. 5, is a fragmentary view of the pump handle shown in Figs. 4 and i, ShOWiIlg' a modification of the handlegripr Like characters of reference refer to like parts throughout the specification and drawings.
The pump consists essentially of a cylinder variation in the changes 0f lob tic i tters f tel f f Patented J y I shame es -'25 1 i comprising Ta cylinuer FcasingQa, cyli .55 heads 6 and-c at the"end'sthereofcoiiple bolts (Z-which hold the cylinder casin cylind r heads intheir assembledfrel'tion, a" I pijst g werking within; the eynnuerga p"' ton: rod i fcr the istcn enteiiding beyc the cylinder" head 0,; and pjlinp 'haiidl z" knuckld to the' outerena rof the piston -rod The cylinder -head I b isprevided with 1 nions b journaled in brackets e, pr' bolt crotherwise rigidlyifastefied o yelatiyely. tacionae iibase are cylindferi r ck ing or osoi'llatiirg 'cluhiii'g the in} iveinen f? the pump handle to compeiisat -f k uckle :during the 'ro'icki l'ig ofthe handle-on itsnucrumms hereinafter 1 w :The pump lmndleii,as F and:3-,"i }fu1crumed the supporting bracket 9''? This racket is preferably bolted or otherwise rigidl f stened-to eaeeuaavaysatienas baser, andis so located that the knuckle of the pump handle is in correct axial alinement with the pump cylinder in all changes of position during the movement of the pump handle.
The lower end of the pump handle a is formed with a curved arm '5 which enters between the forks 2' of the piston rod k, and is connected therewith by a pin i the arm, forks, and pin, constituting the knuckle connection between the pump handle and the piston rod. The long arm of the pump handle consists of two parts Z, Z, the part Z being separable from the part Z. The parts Z, Z are respectively provided with bolts m, m and wing nuts m, m The ends of the parts Z, Z are slotted, the slots m, m receiving the bolts when the parts are assembled, this arrangement forming an easy method of assembling or separating the handle parts respectively for use or storage purposes.
In Fig. 5 the pump handle is formed with a looped handle grip j which is found to be a most convenient type by reason of the facility by which it can be seized and the natural action of the hand and arm during the operation of the pump handle. 7
In the operation of the pump, the handle is rocked upon its fulcrum, and during its movements, draws'the piston rod out of, and then presses it into, the pump; cylinder. During the movements of the handle, the knuckle joint changes its elevation, and this change in the elevation of the knuckle rocks the pump cylinder in its hearings in the bracket 6, Without, however, altering the axial alinement of the knuckle, piston rod, piston and header into the cylinder being prevented:
by the back pressure valves 12 for the outlets ;0, pf
' It is possible to make the bearing brackets e and j of asingle casting or forging,the parts 6, f, and .j in that case being of a unitary character.
By means of a construction of this kind,
1 itis possible toequip an automobile with a stationary pump and operate it with a minimum of power. It is also possible to place the pump within-a pump boxfastened to the running board or some other, convenient part of the automobile, where it will always t Copies of this patent may be obtainedfor five cents each, by addressing the i Washington, D. 0.
my-invention, what I claim as new and desire to secure by Letters Patent, is
An air pump comprising a cylinder having valve-controlled air inlets and outlets,
a pistonoperable Within the cylinder, a pistonrod for the piston extending through one of the cylinder heads and bifurcated at its outer end, trunnions for the other cylinder head, brackets in which said trunnions are journaled, a stationary base for the. brackets, a pump handle formed with Pa curved arm, knuckled to the piston rod, and brackets secured to the base, to Which the pump;handle-is ,fulcrumed above the point of attachment to the piston rod, the pump handle during its operation causing the reciprocating movementof the piston, and the rocking or oscillating. movement of the cylinder, to compensate for the variation in changes of location of the knuckle during the rocking of the pump; handle on its fulcrum.
